Want to buy a flash to shoot cloth bags and clothes, 250w or 400w?

The reason why the background is dark is that the brightness of the lamp is low or the lighting position is not ideal, and your exposure time is fast. The light position can be adjusted, and the camera can shoot with AV file, select aperture, support tripod when the shutter is slow, and then add a little exposure compensation on the basis of the original metering results.

I suggest 400 pounds for the room light. I can turn down the output when the brightness is high, but 250 is not big enough.

If you are sure of the light, the third scheme can also take ideal photos. Otherwise, buy a set to use.

The studio lamp can choose the golden cup, but the three-lamp suit I know is 3 thousand. Jinbei DM2-400 double lamp set licensed 2000 can be done. In addition, there is a JTL 540 watt portable portrait flashing three-light group, which has never been used before. I don't know the truth, but I think it is cost-effective, about 1500. You can look at it online. For reference.
